Does anyone know when they changed the power brake master cylinder cap wording? The early caps have USE DELCO BRAKE FLUID stamped in the cap ,and the later ones have USE DELCO SAEJ1703 BRAKE FLUID. ?? around what month in 69 did they change??

Mine says something completely different. O3B built, power front discs. It reads: WARNING CLEAN FILLER CAP BEFORE REMOVING, and USE ONLY DOT? FLUID FROM A SEALED CONTAINER. Cant read the # after DOT because of pitting.
